Crucial Pro DDR5 48GB (2x24GB) 5600MHz
Who this is for: builders after 48GB of DDR5 at 5600MHz for heavy multitasking, content creation and memory-hungry workloads — it is built for workloads that run out of memory long before they run out of clock speed.
The Crucial Pro DDR5 48GB (2x24GB) 5600MHz is a 48GB DDR5 dual-channel kit rated at 5600MHz with CL46 timings.
At 5600MHz and CL46, the real-world payoff shows up in bandwidth-hungry work such as 1% low frame rates on modern CPUs, code compilation and multi-track editing timelines. Crucial modules come straight from Micron, so the die behind the label is known quantity. Before buying, confirm your motherboard supports 48GB in the configuration you plan to run.

Frequently Asked Questions
Will the Crucial Pro DDR5 48GB (2x24GB) 5600MHz run at 5600MHz out of the box?
Not automatically. Every module boots at a JEDEC baseline first, so you need to enable the XMP or EXPO profile in BIOS to reach 5600MHz at CL46. If the system fails to post, clear CMOS and try one speed step lower.
Is 48GB enough for my build?
48GB is aimed at heavy multitasking, virtual machines, large timelines and high-resolution asset work. For gaming alone it is more than most titles will ever touch.
What does CL46 actually mean here?
CL46 is the CAS latency: the number of clock cycles between a read request and the first data returned. Because 5600MHz clocks faster than older kits, the same CL number represents less real time. True latency in nanoseconds, not the CL figure alone, is what to compare.
Can I mix this with memory I already own?
You can, but it is not recommended. Mixing kits means the memory controller has to find settings that satisfy every module, so you usually end up below the 5600MHz rating. Buying 48GB as a single matched kit avoids that entirely.
